TABLE.

Specification of Letters Patent.

Patented March 19, 1907.

Application filed May 23,1905. Serial No. 261,835.

To all whom it may concern:

Be it known that I, NIOKOLAS E. BROWN, a citizen of the United States, residing at Marion, in the county of Turner and State of South Dakota, have invented new and useful Improvements in Tables, of which the following is a specification.

The invention relates to an improvement in tables, and particularly a self-waiting table, wherein a part of the table is adapted for movement relative to a fixed portion.

The main object of the present invention is to revolubly mount the central portion of the table and also adapt the same for ver tical adjustment, whereby said central portion may be revolved at any desired height to present any required point thereof in the desired relation to the fixed section of the table.

The invention in its preferred form will be described in the following specification, reference being had particularly to the accompanying drawings, wherein Figure 1 is a plan view of my improved table. Fig. 2 is an elevation of the same, and Fig. 3 an enlarged sectional detail illustrating the adjusting means for the movable section.

Referring to the drawings, my improved table constructed of any material desired is preferably circular in plan, the top comprising two sections, a fixedsection 1 and a movable section 2. As shown, the movable section is arranged centrally of the fixed section, the latter being concentric with the movable section and essentially comprising an annular rim or leaf surrounding the movable section. It is understood that the joint between the movable section and fixed section is so arranged that when the sections are arranged in the same horizontal plane they present practically an unbroken surface.

The tablethat is, the fixed sectionis supported upon legs 3 in any desired manner, one of which, as 4, is arranged centrally of the table. At the upper end the leg 4 is formed with a transverse slot 5 and with a vertically-arranged opening 6, extending lengthwise of the leg to the desired distance and communicating at its upper end with the slot 5. The movable section 2 is supported upon a stem 7, depending centrally therefrom and connected at its lower end with a rod 8, formed with a series of circumferentially-arranged teeth 9, suitably spaced apart and formed to project their opposite faces in arranged with their free terminals of the a downward direction. Angle-dogs 10, pivotally mounted at 11 within the slot 5 near opposite ends thereof, are arranged to project their operative ends 12 in position to engage the teeth 9 on the bar 8. The dogs are provided with arms 13, terminally connected through the medium of a spring 14 with one. of the walls of the slot 5. The dogs are so arms 13 under the influence of the springs 14 e normally projecting beyond the plane of the leg 41, as clearly shown in Figs. 2 and 3, whereby said dogs may be operated to release th rod 8, and thereby adjust theemovable eec tion. For convenience in operation ehe 7o movable section is provided with a series bf peripherally-arranged knobs 15, by Which\ the movable section may be conveniently turned on its axis, as will be evident.

In use the movable section may be freely 7 5 elevated to the desired height by an upward pull on the same, as the teeth 9 are arranged to freely pass the dogs 10 in the upward movement of the movable section. When the section has reached the desired height, the dogs will engage beneath the properlysituated. tooth 9 and prevent a downward movement of the section 2. Owing to the circumferential arrangement of the teeth 9, the movable section 2 may be freely revolved 8 5 on the rod 8 without disengaging the dogs 10 thereirom. WVhen it is desired to return the movable sections to a normal position, the h projecting ends of the arms 13 or the dogs are forced inward to the plane of the leg, thereby 9c disengaging the operative ends or the do s from the teeth 8 and permitting the movab e section to move downward to the desired ex tent or to the complete normal position. i

In the abovedescribed construction it is to be particularly noted that I combine with a materially-reduced engaging end of each dog an upwardly-projecting operating-arm, whereby the dogs are released by a downward movement of the said engaging ends, I00 this movement being normally counteracted 'by the springs. This construction materially facilitates the adjustment of the table, as the *eight of the table tends to move the do s into disengaging position, counteracted on y lo 5 by the pressure or the springs.

The table described is particularly useful in ordinary meal service, as it enables the users to revolve the movable section oarryin the food in bulk to bring any article of foo 11o within convenient reach, the knobs 15 serving as effective handholds for the movement of the rod, said dogs comprising normally horizontal members and arms projecting upi l i wardly from the ends thereof and at an m- 1 cline thereto, the upper surface of the mem bers being normally horizontal and being adapted to bear beneath the horizontallyprojected surface oi any of said teeth, the lower edges or" the members being arranged at an incline to the edge thereol and terminating coincident with the tree end of said upper edge, whereby to provide a pointed end for the members to avoid frictional hearing against the sides 0? the teeth, springs secured within the recesses and bearing against the arms o? the dogs to normally l'oree said arms to maintain. locl-1ing position ot the horizontal members, the upward projection of the arms of the dogs serving to permit disengagement of said dogs by a do\\n\\ard movement of the horizontal members, therehr facilitating the adjustment o." the table.
